I linked up with Simon from e-maps this morning for my third car to be mapped by him.

The first two were both petrol variants (E36323i/E46 M3) Whilst these maps didn't deliver massive performance increases, the cars certainly both drove a helluva lot better.

However.... Having just had the 335d transformed this morning, I am still laughing from the gains. It's simply staggering what can be done with a few ecu tweaks. It actually feels quicker than my M3, and that was damned fast.

Totally different power delivery to the M3, but just as addictive.

As always, Simon has vowed to re flash my ecu if the need arises. Lol

I will be going to Germany next month to give it some beans. Any idea what this thing will do top end? I had 176 out of the M3 on the Autobahn, so I am guessing it will be similar.

Re-map is awesome, you'll need Limited Slip Diff next to help put that power down. ;-)
Just beware of dealers re-programming your car - mine got overwritten a month or so ago, and I'm starting to miss it...

Yes, in the UK I would seriously consider it Especially for the increased refinement and economy that people report as much as vastly improved pace.

But where I am has simply draconian Police (with guns, small dicks and no sense of humour whatsoever) that literally hide in bushes, and have specialised camera/radar cars to nab you and make money. You just never know where they are hiding (detectors are illegal). But usually at the optimum place to catch you out - not black spots.

Thankfully you only get a fine, no points. The amount of fine is graded - one friend got caught at slightly silly speeds and paid a staggeringly huge amount and got a suspended 2 year jail sentence, he's now driving like Miss Daisy. I even got caught in a 10km/h Parking zone racing about at 16km/h ... Bloody reckless, I am.

My usual journey is almost exclusively city driving (50 km/h ~30mph) and the odd A road (80 km/h ~ 50 mph) so having the already quick 335D even faster would just be frustrating.

Hmm. Not sure about that. Mine is a Jan 08 build and there was no problem. Maybe the later ones are different, but I can't see why.

Sounds promising, since mine is a Jan or Feb build. Just emailed Simon at Emaps to confirm. There was speculation that BMW were moving to the new Bosche V17 ECU which has yet to have the encryption broken.

You should see 175mph at best. However, you will need the car to be in manual mode to achieve it and you will need to change up at approx 4200rpm with the car in fifth as it will not change up on it's own beyond that. If you leave the car in "D" then 5th at 4200rpm will be about as far as it goes and that's around 153-155mph.

The car will accelerate well upto 153-155mph, but then due to knocking it into 6th at 4200rpm (in 5th), it will slowly climb to around 165mph, before picking up a bit better for the surge from 165-175mph.

I'll be putting this to test at Bruntingthorpe in a couple of weeks time so will let you know how I get on.

Thought I'd update this post of mine.

Firstly the contents of my post above are wrong!! (That'll teach me to listen to theory without putting it into practice first.)

I went to Bruntingthorpe at the weekend for the VMax event, unfortunately my remapped 335d would still not pull past 155mph, which is approx 4100rpm in 6th (and not 5th as I had been told!!). The guy who tuned the car was also there and checked the map to ensure that the limiter had been raised and it had, for good measure he raised it further (??), but it made no difference, the car would just stop at 155mph. The Tuner said that there was not much more he could do but explained that when the infamous DMS 535d was recorded at 175mph at Nardo Testing Track it too seemed to halt progress at 155mph before eventually kicking on again to 175mph, but needed a further 2 miles to achieve this. Bruntingthorpe is only 1.6 miles and I had probably hit 155mph with a half mile left to travel....so maybe more distance needed?

Has anyone with a remapped 335d taken it beyond 155mph?

There were still many highlights on the day, one being the run I had against the new V8 M3. I outlaunched him but by the end of the first straight (1/2 mile approx) he had gone a couple of lengths up, I managed to get back in front around the 180 deg bend and had a car lengths advantage at the exit (exit at about 75mph), over the next 1.6 miles he managed to just edge by me very slowly and eventually was only 3 car lengths in front with the gap holding station by the end.
